retrieve particular column between different columns of sqlite databse in android

Here is the code, by this I can retrieve all the columns data from the database. But the problem is that now I want to retrieve only one column, that is my requirement.link1st link 2nd link3rd
word_list = new ArrayList<>();
SQLiteDatabase sd = mydb.getWritableDatabase();
Cursor cursor = sd.query("stickerstable",null, null, null, null, null, null);
if (cursor.moveToFirst()){
do{
word_list.add(new data_items(
cursor.getInt(cursor.getColumnIndex(ID)),
cursor.getString(cursor.getColumnIndex(STICKER_AUTHOR)),
cursor.getString(cursor.getColumnIndex(STICKER_NAME)
)));
}while (cursor.moveToNext());
cursor.close();
sd.close();
}

You can use rawQuery instead of query
Cursor cursor = sd.rawQuery("SELECT YOUR_COLUMN FROM stickerstable",null);
replace YOUR_COLUMN with the name of column you want to retrieve you can even use your Constants like this
Cursor cursor = sd.rawQuery("SELECT " + ID + " FROM stickerstable",null);
or a better way to use String.format
Cursor cursor = sd.rawQuery(String.format("SELECT %s FROM stickerstable", ID),null);
UPDATE
you can use query and specify the column in the second argument
Cursor cursor = sd.query("stickerstable",new String[]{ID}, null, null, null, null, null);
when you pass null means get all columns

the _id column of MMS-SMS database

I am accessing Android MMS-SMS database:
Uri.parse("content://mms-sms/conversations?simple=true");
ContentResolver contentResolver = getContentResolver();
String[] projection = {"_id"};
Cursor cursor = contentResolver.query(uri, projection, null, null, null);
//Is the id the same as the id in corresponding SMS or MMS table?
long id = cursor.getLong(cursor.getColumnIndex("_id"));
My question is simple, is the "_id" column holds the same id value of corresponding table (for SMS "content://sms"; for MMS "content://mms") ? If it is not, how can I get the id of the message in SMS or MMS table from the cursor I got?
What I want to do is I want to use this id to query the corresponding SMS or MMS table.

Do you want fetch mms-sms by "_id" column from "content://mms-sms/conversations?simple=true"
try
Cursor cursor = getContentResolver().query(Uri.parse("content://mms-sms/conversations/"+id), new String[] {"_id","body","date","type","error_code","ct_t","_data","m_type"}, null, null, null);
"id" is value "_id" column.

I think you are doing that in wrong way. You should add your wanted values about sms to the projection like that;
String[] projection = {"Conversations._ID"};
then you can take sms id with that:
long id = cursor.getLong(0);
If you want to take another information from Sms, add your keys to projection like:
String[] projection = {"Conversations._ID", "Conversations.ADDRESS", "Conversations.BODY"};
then;
long id = cursor.getLong(0);
String address = cursor.getString(1); // tel number
String body = cursor.getString(2); // content of message
Edit: You should also check your uri and try that:
Cursor cursor = contentResolver.query(Conversations.CONTENT_URI, projection, null, null, null);
Good luck.

Display the Contacts in sorting order ContactsContract.Contacts of Content Resolver

My intention is to display the contacts in sorting order using content resolver in android.
For that I'm writing:
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID+ " = ?", new String[] { id }, null);
It needs that the last parameter in query method should not be null for sorting the elements by Name. Which part of code I have to replace the null parameter to achieve sorting by name?

To sort result according to name use Phone.DISPLAY_NAME constant with ASC as last parameter to query method. do it as:
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID+ " = ?",
new String[] { id },
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME+" ASC");

It would be better to use SORT_KEY_PRIMARY or SORT_KEY_ALTERNATIVE on API level 11 and later.
Cursor cursor = getContentResolver().query(
ContactsContract.Contacts.CONTENT_URI,
null, null, null,
ContactsContract.Contacts.SORT_KEY_PRIMARY + " ASC");

You can use Upper() to sort for both lower as well as upper case contact name.
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
null, null, "upper("+ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + ") ASC");

The ContentResolver.query() method takes many arguments but to sort the content provider records, you have to edit the last argument of this method.
It should be like this:
Cursor cursor=getContentProvider().query(.......,"DISPLAY_NAME ASC")
This will arrange the contacts in Ascending order of their name.
Note: This argument should be in a String datatype.

You can use the Desc string using these lines to sort out to see the recent contact
android.database.Cursor cursor = getContentResolver()
.query(android.provider.ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null, null, null,
ContactsContract.Data.CONTACT_LAST_UPDATED_TIMESTAMP +" DESC");

Sqlite database retreival of multiple data

In sqLite,i have 3 values inserted in a table in my database ,from an activity.
I need to reteive those 3 values from the database,from another activity...The retreival of the first value from the table is possible..i cant retreive the remaining 2 values...How can the cursor object be defined to do the same???
myDB = MyService.this.openOrCreateDatabase("antitheft", MODE_PRIVATE, null);
Cursor cursor1 = myDB.query("SimSerial", null, null, null, null, null, null);
cursor1.moveToLast();
String ss1 = cursor1.getString(cursor1.getColumnIndex("simno"));
cursor2.moveToFirst();
String num1 = cursor2.getString(cursor2.getColumnIndex("secure"));

You can write the query for selecting all the records and then iterate through the records.
Cursor cursor1 = myDB.query("SimSerial", null, null, null, null, null, null);
cursor1.moveToFirst();
while(!cursor1.isAfterLast()){
cursor1.getString(....);
cursor1.moveToNext();
}

You need to iterate cursor. For that you can use following example.
Cursor cur = myDB.query("SimSerial", null, null, null, null, null, null);
cur.moveToFirst();
while (cur.isAfterLast() == false) {
String str = cur.getString(1);
cur.moveToNext();
}
cur.close();

Query only the first data from a table

I'm trying to query only the first data from the table.
Cursor img_cursor = db.query(
IMAGE_URL_TABLE_NAME,
new String[]{"small_img_url" , "large_img_url"},
null",
null, null, null, null);
Could somebody tell me how to implement a query where only the first data is retrieved from a table?
Solution
I think I solved the answer:
Cursor img_cursor = db.query(
IMAGE_URL_TABLE_NAME,
new String[]{"small_img_url" , "large_img_url"},
null",
null, null, null, null , "1");
I used limit 1 first, but the application crashed. Only if I pass the number as a String will it work. The query has 8 parameters while we're using the limit parameter.

limit 1
From Documentation:
public Cursor query (boolean distinct, String table, String[] columns, String selection, String[] selectionArgs, String groupBy, String having, String orderBy, String limit)
so, put your last argument to be "limit 1".
Cursor img_cursor = db.query(
IMAGE_URL_TABLE_NAME,
new String[]{"small_img_url" , "large_img_url"},
null,
null, null, null, "limit 1");
